Abstract

Stent, insbesondere Koronarstent, bestehend aus mindestens einem dünnwandigen, rohrförmigen Körper (2), dessen Mantelfläche (1) in stegartige, sich in Längsrichtung des Stents erstreckende und in Umfangsrichtung des Stents expansible Elemente (4, 4', 4", 4"', 4"") unterteilt ist, die über jeweils wenigstens einen Verbindungssteg (6, 6') mit den beiden in Umfangsrichtung des Stents benachbarten expansiblen Elementen (4, 4', 4", 4"', 4"") und über einen stirnseitigen Anschluß (8) mit der Stirnseite (4.4') eines in Längsrichtung des Stents angrenzenden expansiblen Elements (4, 4', 4", 4"', 4"") verbunden sind, wobei die Mantelfläche (1) im nicht expandierten Zustand im wesentlichen frei von Ausnehmungen ist und durch Trennfugen (3) unterteilt ist, die im Verhältnis zur Stegbreite der expansiblen Elemente (4, 4', 4", 4"', 4"") eine wesentlich geringere Breite aufweisen, sowie Verfahren zu seiner Herstellung.

Figure 00000001
Stent, in particular coronary stent, consisting of at least one thin-walled, tubular body (2), the jacket surface (1) of which is made up of web-like elements (4, 4 ', 4 ", 4"' which extend in the longitudinal direction of the stent and are expandable in the circumferential direction of the stent , 4 "") is divided, each via at least one connecting web (6, 6 ') with the two adjacent expandable elements in the circumferential direction of the stent (4, 4', 4 ", 4"', 4 "") and via one The end connection (8) is connected to the end face (4.4 ') of an expansible element (4, 4', 4 ", 4"', 4 "") adjacent in the longitudinal direction of the stent, the outer surface (1) being in the unexpanded state is essentially free of recesses and is divided by parting lines (3), which have a much smaller width in relation to the web width of the expansible elements (4, 4 ', 4 ", 4"', 4 ""), and methods for its Manufacturing.
